以浮点型表示的两个datetime.time (HH:MM)值之间的分钟差

import datetime

def calculate_minutes_difference(time1, time2):
    # 将时间字符串转换为datetime对象
    datetime_format = "%H:%M"
    datetime1 = datetime.datetime.strptime(time1, datetime_format)
    datetime2 = datetime.datetime.strptime(time2, datetime_format)

    # 计算时间差
    timedelta = datetime2 - datetime1

    # 提取分钟差
    minutes_difference = timedelta.total_seconds() / 60

    return minutes_difference

# 示例用法
time1 = "09:30"
time2 = "12:45"
minutes_difference = calculate_minutes_difference(time1, time2)
print("时间差为", minutes_difference, "分钟")
